Identifikasi Molekuler Gurita (Family: Octopodidae) dari Perairan Lombok Berdasarkan Marka Gen Sitokrom Oksidase Sub Unit I
Full text linkLombok waters are a potential commodity area for fishing. One of the potential commodities caught is the octopus species from the octopodidae family. A recent study revised the generic taxonomy of the Octopodidae family, and several groups of species previously included in Octopus are now recognized as independent genera. However, knowledge of the phylogenetic relationships among taxa in the Octopodidae family is still lacking. This study aims to identify octopuses belonging to the genus Octopus in Lombok Waters, namely: Sari Gong Beach, Ketapang Beach, Beraringan Beach, Cemara Lembar Beach molecularly. The study was conducted from January to June 2024. Octopus samples caught by fishermen were analyzed morphologically and molecularly. The study will be conducted for 6 months from January to June 2024 in Lombok Waters. Octopus sampling was carried out once a month, observations representing the conditions of the dry season and rainy season with an interval of 30 days. The research methods used include: octopus sampling, identification, molecular identification, alignment of 16S rRNA gene nucleotide sequences, genetic distance. It is hoped that this study will be useful for providing basic information on octopus species belonging to the genus Octopus found in Lombok Waters. This information can be used for further studies on octopus biology, octopus resource potential, and studies on octopus resource management strategies in Lombok Waters. The octopus species caught in Lombok Waters were identified morphologically and molecularly as Octopus cyanea. In addition, the nucleotide base sequence can be used to design specific COI gene primers for O. cyane

Echoes of the Thai Accent: Examining Its Impact on English Learning and Teaching Strategies
Full text linkThis study examines the challenges faced by English teachers in Thailand when teaching students with a Thai accent and explores the strategies they employ to address these difficulties. The phonetic differences between Thai and English often lead to pronunciation difficulties, comprehension issues, and reduced self-confidence among students. Using qualitative methods, this research gathered data from interviews with three English teachers at Tessaban 2 Bansadao School. The findings indicate that limited English exposure, difficulty distinguishing certain phonemes, and the influence of Thai tonal and intonation patterns significantly hinder students’ learning. In response, teachers implemented phonetic drills, multimedia-assisted instruction, and various communication techniques to enhance pronunciation and engagement. Rather than focusing on accent reduction, the study emphasizes the importance of intelligibility in spoken English. By identifying accent-specific teaching strategies, this research contributes to more effective instructional practices for Thai-accented learners of English, ultimately improving their pronunciation and overall language skills

Sustainable Tourism Development in the Mandalika Special Economic Zone: A Comprehensive Analysis of Social, Economic, and Environmental Impacts
Full text linkThis study aims to analyze the implementation of sustainable tourism development in the Mandalika Special Economic Zone (KEK), Central Lombok, and its impacts on social, economic, and environmental aspects. As an area prioritized in the development of super-priority destinations by the Indonesian government, the Mandalika SEZ is an important case study in seeing how the principles of sustainable development are applied in the tourism sector. This study uses a descriptive method with a qualitative approach that relies on secondary data from various previous literature sources, government reports, and relevant documentation. Data analysis was carried out with the help of Nvivo 12 Plus software to group key themes and understand patterns in the data collected. The results of the study show that development in the Mandalika SEZ does not only focus on physical and infrastructure aspects but also includes empowering local communities through strengthening the Micro, Small, and Medium Enterprises (MSMEs) sector, such as agriculture, coffee entrepreneurship, and handicrafts. Tourism has been shown to contribute significantly to local economic growth, creating jobs and increasing community income. This is reflected in the increase in the Human Development Index (HDI) of Central Lombok, which reached 67.57% in 2022. From the environmental side, air and soil quality indicators show significant improvement, with the target of increasing the ecological quality index by 43.31% in 2026, running according to plan, and reaching 43.03% in 2023. Tourism development in the Mandalika Special Economic Zone shows a positive direction in realizing sustainable development. A comprehensive approach to social, economic, and environmental aspects shows that tourism development can be a strategic instrument in improving the quality of life of local communities while preserving the environment
Micro and Small Enterprises of Former Combatants: Behind Economic Contributions and Problems to Transforming Peace in the Affected Conflict Community of Aceh
Full text linkThis study analyzed the positive effects behind micro and small enterprises (MSEs) empowerment programs of the former combatants - the Free Aceh Movement (GAM) despite its problem, on transforming Aceh conflict to a positive peace. MSEs play a critical role in contributing not only to economic empowerment but also conflict transformation and sustaining peace especially during the post peace agreement, that granted Aceh a form of decentralization of power from central government, with a significant degree of political and economic autonomy. Indonesia. Although the MSEs in rural Aceh Province most of them failed, they have positively contributed to the sustainable peace in the region. Based on this assumption, this study explores the ex-combatant's experience with the MSEs program within the framework of decentralized power, and how the program gradually brought them back into the community. In-depth interviews, and field work observation, were the main techniques of the data collection. The data analysis was done using thematic analysis. The study found that autonomy and decentralization has created new political marketplace. MSEs that were set up in small groups of former combatants, civilian victims and other interested community members, was used to build patronage network and that led to their failure. However, the interactions occurring in operating these MSEs have re-established the relationships among the former combatants, victims, and ordinary people that were broken during the conflict. Thus, MSEs gradually reintegrated those ex-combatants into the community
Analisis Kerusakan Mesin Thresher pada PT Socfindo Seunagan Menggunakan Metode Failure Mode And Effects Analysis (FMEA)
Full text linkThis study aims to analyze the damage of the Thresher machine at PT Socfindo Seunagan using the Failure Mode and Effects Analysis (FMEA) method as an effort to identify potential failures, causes, and impacts on the production process. The scope of the study focused on four main components of the thresher machine, namely the thresher drum, shaft and bearings, chain, and gearbox. The research method employed a combination of interviews, direct field observation, and literature reviews. Data analysis used the FMEA approach by determining the type of potential failure, causes, effects caused, control efforts, and calculating the Risk Priority Number (RPN) to determine repair priorities. The results showed that the damage that often occurred included bending/breaking in the thresher drum, cracks in the shaft and bearings, breaks in the chain, and cracks in the gearbox. The highest RPN value was found in the gearbox component at 224, followed by the chain with a value of 96, the thresher drum at 42, and the shaft and bearing at 36. This indicates that the gearbox is the most critical component that requires special attention in care and maintenance. The conclusion of this study is that thresher machine failure has the potential to significantly reduce CPO processing productivity if proper control is not implemented. Therefore, companies need to implement routine maintenance and periodic checks, with a primary focus on the gearbox components, to minimize the risk of damage, extend the machine's lifespan, and maintain optimal production flow
